PUTTYLESS GLASS ROOF Filed April 19, 1930 2 Sheets-Sheet 2 vwantozaww/tug Patented Nov. 26, 1935 UNITED STATES PATENT OFFICE 2 Claims.

My invention relates to'improvements in puttyless glass roofs orcomposition roofs, and it has for its object to provide a roof in whichno putty is used in its construction, and where the same may beconstructed of glass, sheet metal or other sheet material and assembledand connected Without producing leakage.

My invention especially relates to sky-light roof formations, includingglass roofs for green houses and for operating rooms in hospitals, orfor similar purposes in any other building.

With these objects in View my invention con sists of certain novelfeatures of construction and arrangement of parts as will be hereinafterfully described and pointed out in the claims. Reference being had tothe accompanying drawings, in which:-

Fig. i is a plan View of my device.

Fig. 2 is an end fragmentary view of my devlce.

Fig. 3 is a side View of a part of my device, partly in cross section.

Fig, 4 is a side View of a fragmentary part of my device, partly incross section.

Fig. 5 is a side view in fragmentary form, partly in cross section of amodified form of my device.

The same reference characters denote like parts in each of the severaliigures of the drawings.

In my construction, as shown in Fig. l, the glass surface is composed ofsheets represented by A, and may be so laid on as to have oneoverlapping the other if desired.

In constructing my device, I have a series of rails B, B, B, formingtrusses adapted to be spaced apart at any given distance for the supportof sheets of glass or other roof materials for the roof structure.'These rails are of the structure and formation as shown by the end Viewof the same in Fig. 2, and a side View of the same, as shown in Figs. 3,4 and 5, and having the two vertical' side wall projections 2, 2, spacedapart and forming an interior longitudinal recess il and having thebottom Il. The said rails B, B have on each side the horizontallyprojecting outer side flange 5, and each of said outer flanges have anouter spaced apart upturned edge 6, from the flange 5, as shown in Fig.2. At the upper edges of the vertical sides 2, 2, of rails B, there areprojected inwardly projecting flanges 1, on the upper surfaces of saidange projections 'I I have a horizontal curved channel 8. The inneredges of projections l, I are spaced apart from each other and leavingan open channel 9.

As a further part of construction of my device,

I have removably mounted in the horizontal channels 8, 8 a section orportion of tarred rope or cord, or other substance impervious to waterIIJ.

As a further part of my device, I have vertically 5 and removablymounted in the channel 9 of rail B the bolt II, its lower end resting onthe bottom 4 in channel 9, of rail B, as shown in Fig. 2 and Fig. 4.

At the lower edge of my improved roof strucl0 ture I provide angularlugs I2 having upturned edges I3 as shown in Figure 4. These lugs I2have threaded openings through Whichthe lower row of bolts II pass aswill also be obvious upon reference to Figure 4. Upon turning of thebolts I I the lugs I2 will be drawn upward to contact vwith the loweredges of flanges 1`l. The upturned edges I3 of the lugs serve as stopsfor the lower row of glass plates or sheets during the assembly. Thebolt II may be provided with an enlarged polygonal nut I3 as shown inFigure 2 and the inner ends of the glass plates A are adapted to restupon the yielding material II) also shown in Figure 2.

With the bolts intermediate the ends of the roof surface as shown inFigs. 2 and 3, the angular lugs I2 do not have the upturned edges I3, asthey are unnecessary.

As a further part of my device I have the elongated capi I4, having theouter extending edge flanges I5, which flanges rest upon the surfaces ofthe glass plates A near their contiguous edges, as shown in Fig. 2. Inconstruction the cap I l has openings therein as at I6. The upper end ofbolt II projects vertically and the nut I3 may be 35 mounted thereon andis adapted to draw down cap I4 with its flanges I5 to contact with thesurface of the glass A.

In the construction of my device, it is designed that the rails B havingthe rail bottoms 4l, 4.0 which rest upon the cross beam C of the roofstructure, and are there held in place by the step clamps I'I, II, Thelower end of the clamp has thru it the bolt I8, projected into beam C,While the upper end of I'I has thru it the bolt I9, which 4.5 bolt I9passes thru the sides 2, 2 of rail B, and has mounted thereon the nut20, as shown in Fig. 2. Such construction is adapted to draw the clampto iirm position tothe sides 2, 2, of rail B, and hold the rail in firmcontact with the roof structure.

As a further part of my device, and projected horizontally along theupper edge of my roof structure, I have the flap 20', extending over theupper edge of glass section A, and having downward projecting lugs 2|integral therefrom :and spaced apart which extend over the upper surfaceof caps I4, I4, as shown in Fig. 1. Said flap 2D has also integraltherewith a vertical projection 22, adapted to extend up under a siding23, of a building when the upper edge of the roof is adjacent to anunder side wall as shown in Figs. 3 and 5. The flap 29 has a projectedend portion 24 which is adapted to be bent over so as to projectvertically downward and against the outer surface of cap I4 and thesides of the roof structure to prevent leakage therein.

As a further part of my device, it is designed that in certain forms ofroof structure where the glass A is placed in layers overlapping eachother to have the rail B vertically stepped in formation, as shown inFig. 5, and adapted to permit one section of glass A to overlapk theedge of the lower adjacent glass plate A, as shown in Fig. 5,'- in whichstructure the cap i4 of the roof structure at the point 25 is also bentin step formation, as shown in Fig. 5, to be adapted to the outersurface of the roof structure.

As a further part of my device, I have an outer side cap 26, adapted tobe bent over and mounted on the outer surface of an end roof rail B, asshown in Fig. 4, to protect the outer end surfaces of the roof structurewhen completed.

Having thus described my invention, what I claim as new, and for which Idesire Letters Patent is as follows:

1. In a puttyless glass roof, a plurality of parallel girders spacedapart, each girder formed with a channeled upper surface, supportingmeans for the girders, rows of glass plates supported by the girders,the edges of the glass plates resting on the girders and spaced apart,elongated caps disposed along the girders and hav- 5 ing anges engagingadjacent rows of glass plates, means for clamping the caps upon theplates, and lugs in the lower ends of the girders and having upwardlyextending portions outside of the girders against which the lower row ofglass plates abut, said lugs being connected to a part of the clampingmeans for the top plates.

2. In a puttyless roof of glass and the like, a plurality of parallelgirders spaced apart, each girder having a channel in its upper surface,supporting means for the girders, rows of glass plates supported by thegirders, the edges of the glass plates resting on the girders and spacedapart, elongated caps disposed along the girders above the glass platesand having flanges engaging adjacent rows of glass plates, means forclamping the caps upon the plates, angular lugs having portions disposedin the lower ends of the girders and having upwardly extending portionsabutting the ends of the girders and projecting above the same toprovide stops for the spaced apart edges of the lower row of glassplates, and threaded bolts passing through the cap and threaded throughthe portions of the lugs within the channels for clamping the loweredges of the plates and the channels'together.
